I just took a quick look at the page and did some analysis with the SeoMoz toolbar - you can download that as a chrome extension and its brilliant for a quick healthcheck on your individual pages.

The first thing I noticed was that you have the Title tag <Title> as your business name - The Electric Heating company. I would start with immediately changing that to Include your keyword at the beginning.

I only checked a few of your pages, but all were named with your business. A classic no-no as Google definitely uses the title tag to find out what your page(s) are about.

Another thing, you have a couple of images on there named radiator3 and radiator4...consider renaming those images and adding alt tags to include 'electric radiators for conservatories and EHC Electric Radiators.

I also noticed you have a wordpress site. I'd really recommending adding the Yoast Wordpress SEO plugin. That trains you how to optimise your pages and I have had great success with that.

Hope that helps - that will definitely help you get ranked for the term.

When I checked (and I've just checked again), the real time results show that the title tag is showing the company name. If you, or another person have made these changes, they haven't been saved and effected the change.

I've attached a screenshot of keyword analysis for that page - only showing critical and high factors. You can see that it references the Title Tag in two areas as being unticked.

The number 2 in your url will be fine and shouldn't cause you any issues at all. As a starting point, your title tag and your images titles and alt tags should resolve it. You can then work at marketing that page etc.

I would really recommend the moz toolbar, I don;t think I could live without it to be honest! When you know what you are looking for, it tells you exactly what you need to know in an instant.
